CHROMATOGRAPHY & SPECTROSCOPY
Reliable Method for Rapid and Accurate Analysis of Trace Elements in Honey
Thermo Fisher Scientific, Inc announced a new robust, reliable method for analysis of trace elements in honey by atomic absorption. The Thermo Scientific iCE 3500 atomic absorption spectrometer offers a unique dual atomizer design, which allows automatic, efficient and safe switching between flame and graphite furnace analyses without the need for user intervention or alignment adjustment.
By utilising the system’s flame and furnace methods, users can undertake both high level and low level analyses on the same instrument. The flame sample introduction system is able to efficiently run dissolved honey samples without blockage or contamination, while the furnace system handles acid digested samples with ease.
The viscous and sugary nature of honey makes it a difficult substance for quantitative trace elemental analysis. This new application note demonstrates how flame and graphite furnace absorption spectrometry can be utilized to facilitate faster analysis while reducing operational costs.
The iCE 3500 Atomic Absorption Spectrometer is a permanently aligned, true dual atomizer enabling rapid switching between flame and furnace methods without user intervention resulting in improved productivity.
The instrument is also the only spectrometer on the market to offer both Deuterium and Zeeman background correction providing guaranteed performance and flexible interference-free furnace analysis. The advanced integrated furnace autosampler also speeds up analysis by automatically preparing working standards from a single master standard and adds matrix modifiers to samples prior to analysis.
The iCE 3500 Atomic Absorption Spectrometer provides outstanding performance and flexibility in an easy-to-use and compact system. The Graphite Furnace TeleVision (GFTV) furnace vision system offers high definition images of the events taking place inside the graphite furnace cuvette for optimised sample deposition and method development. Concurrent operation of the furnace, and autosampler sampling procedures minimises the overall furnace cycle, while the high precision, double beam optics of the iCE 3500 provide low detection limits and analytical stability.

High Pressure Chemical Reactors
Supercritical Fluid Technologies introduces a new series of stirred reactors for high- pressure chemistry. The HPR Series Reactors have been designed for researchers who are interested in performing pressurised chemical reactions in their laboratories. Whether it is high-pressure chemical synthesis or process development, the HPR Series is an excellent unit for those applications.
The reactors range in size from 50ml to 4 litres and may be operated up to 10,000 psi and 350°C. The reactors have a magnetically coupled impeller for optimal mixing. All high- pressure components are ASME rated and protected by a rupture disc for safe operation. These laboratory bench top models are ideal for applications where repetitive use makes convenience a necessity, such as catalytic studies, polymerisation, hydrogenation, oxidation, isomerisation, and dehydrogenation. All sizes are supplied as ready-to-use instruments requiring only utility connections prior to operation. The reactors are compact instruments that fit easily into a fume hood. Their modular design makes it simple and cost-effective to alter the unit’s basic configuration to adapt to new or evolving application needs.
All functions for the HPR Series Reactor are controlled by choices of two integrated processors (RxTrol Jr. or RxTrol Sr.) with a full colour touch screen. RxTrol Jr. consists of (2) temperature sensors (wall/interior mounting), and fuzzy logic PID temperature controls and mixing controls in a table top assembly. RxTrol Sr. offers many more advanced features utilising a microcontroller to perform all PID, ramp/soak, process trending, and interlock functions.
Additional options include vessel windows (<150o C operation only), additional ports, cooling
coils, sample loops, stand alone pressure transducers, supercritical fluids pumps and reagent addition modules.
